The VX-II with Roman numerals was discontinued YEARS ago and replaced with the VX-2 with Arabic numbers. If it is really the VX-II with Roman numerals I'd pass. It is just too old.
And even the VX-2's have evolved over the years. If the adjustment knobs are click adjustable it is a newer VX-2 made in the last 8-9 years. Many of the original VX-2's had friction adjustment and those can be quite old too and I'd have to pass.
The only difference between the Rifleman, VX-1, and VX-2 were the options available on them. The glass was always the same. But the Rifleman and VX-1 were basic scopes. If you wanted different options such as CDS or different reticles you had to pay more for the VX-2.
A couple of years ago Leupold streamlined their offerings. The current VX-Freedom replaced the VX-2, but with fewer options to choose from. The lower priced Rifleman and VX-1 versions were discontinued. It is a good scope, just as good as a recent VX-2, and a lot better than a VX-II. But even if it is a VX-2 it could be 15 years old or more. Given the same quality scope new I'd go with the new VX-Freedom
FYI, there is no such thing as a 4X12X40 scope. It is a 4-12X40 scope. There is a huge difference in the meaning when it is written incorrectly.
